![]() Flush or rinse all products with sterile saline or a similar solution prior to use. Angioplasty techniques varied slightly according to individual operator preference.Precautions to prevent or reduce clotting should be taken when any catheter is used: Angioplasty is used to treat venous stenosis affecting dialysis access, with drug-coated balloon angioplasty proving to have better 6 month and 12 month patency than conventional balloon angioplasty. Stents that are used in conjunction with a balloon catheter are known as balloon expandable stents, as opposed to self-expandable stents, typically made of Nitinol alloy.The Athletis™ PTA Balloon Dilatation Catheters are not intended for injection of contrast medium.To prevent over pressurization, use of a pressure monitoring device is recommended. When the cardiologist subsequently deflates the balloon, the stent stays behind in the artery and the balloon catheter can be removed. Screening was done by ultra- sonography, with angiography reserved for patients with hemodynamically significant stenoses, to assess the degree and location of. Atherosclerosis is a condition in which a material called plaque builds up on the inner walls of the arteries. This procedure improves blood flow to the heart. When the cardiologist inflates the balloon it expands the stent. Coronary angioplasty is a medical procedure in which a balloon is used to open a blockage in a coronary (heart) artery narrowed by atherosclerosis. Balloon catheters are supplied to the cath lab with a stent pre-mounted on the balloon. Balloon catheters are also utilized in the deployment of stents during angioplasty. When a balloon catheter is used to compress plaque within a clogged coronary artery, it is referred to as a plain old balloon angioplasty or POBA. While OTW Catheters may still be useful in highly tortuous vascular pathways, they sacrifice deflation time and pushability. Rx catheters nowadays are about 90% of the Coronary Intervention market. ![]() pyeloplasty using a detachable inflatable balloon stent positioned via a cystoscopic transvesicular approach.īalloon catheters used in angioplasty are either of Over-the-Wire (OTW) or Rapid Exchange (Rx) design. ![]()
